HEEL-SOOURING GUARD.

To all whom it may concern:

Be it known that we, SILAs W. DERBY and HAROLD L. DERBY, citizens of theUnited States, and residents of Kirksville, in the county of Adair andState of Missouri, have invented a certain new and useful Improve-- mentin Heel-scouring Guards, of which the following is a specification.

Our present invention relates to improve heel scouring machines whichwill prevent the uppers of the shoes from becoming dam aged by theabradant, and in' general faoili-j tating the manufacture of shoes.

Another object of our invention, is to provide guards of the characterdescribed.

which are movably mounted in close proximity to the abradant, each guardbeing capable of movement in a path transversely of the abradant andacted upon to normally, but yieldably present an element to pro ect intothe rand or space between the heel and lupper of the shoe, so as toextend beyondthe periphery of the abradant, the desired distance, theoperator positioning the shoe to be acted upon with said elemententering the rand with the heel nearest the abradant, followed by movingthe shoe bodily into engagement with the abradant, oscillating orotherwise moving the shoe to accomplish v the end in view. Since thesaid element must be moved from normal position in order to permit the,heel to engage the abradant, the operator is enabled to more readilycontrol the pressure of the heel against the abradant.

Other objects of our invention will appear in the following detaileddescription, taken in connection with the accompanying drawing, forminga part of this specification, and

in which drawing Figure 1 is a side elevation of that portion of a heelscouring machine of the type including a revoluble drum-like membercarrying the abradant, and showing a guard embodying our inventionapplied thereto.

Fig. 2 is a sectional View through the mandrel of the machineintermediate the revoluble abradant and the guard.

Application filed September 5, 1916. Serial N 0. 118,461.

Fig. 3 is a central vertical sectional view through the guard.

Fig. 4: is a perspective view of a carrier, forming a part of the guard.

Fig. 5 is a sectional view on the line 5-5 of Fig. 2, through the guard.

Fig. 6 is a perspective view of the shoe engaging member of the guard.

Inthe drawing, where similar characters refer to similar partsthroughout the views, A designates a heel scouring machine in cluding abearing B, mandrel C carried thereby, and drum-like member D, theperiphery of which carries an abradant, such as sand; and E a guardembodying our invention and comprising a support F, preferably annularinshape, G a guard plate for engagement with the shoe, H a carrier forsaid plate movably supporting the same from support F, J a stop limitingthe amplitude of movement of carrier H in one direction, and K a device,such as a spring, yieldably retaining said carrier in operative relationto the stop J, and yieldably resisting movement of said carrier in onedirection.

In the example shown, the support F is provided with a transverseopening 7 to receive the end. portion'of bearing B, and in practice isdisposed between the drum-like member D and bearing B in a manner to beadjustable circumferentially of the mandrelC, set screws 8 beingprovided to retain the support in a rigid adjusted position with respectto the bearing B. The opening 7 is of such asize as to receive themandrel C with considerable latitude thereabout, as is clearly shown inFig.2 of the drawing, the face 9 of the support confronting one face ofthe. drum-likeImember D, and in close proximity thereto.

Referring now to the carrier H, it is preferably made of a relativelyfiat arcuate piece of metal, the carrier extending about the opening 7,with one end portion pivotally connected with the support at face 9, asby screw 10, the stem of which enters a screwthreaded bore 11 open tothe face 9 of support F. Thus the carrier may be swung toward or fromthe mandrel C, however, being arcuate in shape, it has a considerableamplitude of oscillation about the axis of screw 10 without engagingsaid mandrel.

As to the guard plate G for engagement with the'shoe, it is secured tocarrier Has by screws 12, the shanks of which enter screw-threaded bores13 in the carrier H, the heads of the screws being received incounter-sinks 1i in the plate G. This plate is preferably of such awidth as to provide an arcuate portion 15 to enter the rand or spacebetween the heel and upper of the shoe. When assembling the plate G intooperative relation to the guard and drum-like member I), it is disposedat the outer face of carrier H and next adjacent to the confronting faceof member D, so as to be in close proximity to the periphery of saidmember.

In order to limit the amplitude of move ment of the carrier H in onedirection, the stop J is provided which may be formed integral withsupport F and the stop J carrying a flange 16 which engages the outerface of carrier H, preferably at its free end portion, preventingmovement thereof away from the face 9 of support F. The stop J- is sopositioned that, when the carrier H engages the same, the arcuateportion 15 of plate G follows, but is removed from the periphery ofmember D as is clearly shown in Fig. 2 of the drawin Referring now tothe device K, it is preferably in the form of an expansion springdisposed in a recess 17 open to the face 9 of support F, said recessbeing to one side of the opening 7 The carrier H may be provided with alug 18 extending into said recess, and provided with a centering pin 19about which a convolution of the spring extends. A centering pin 20 mayalso be carried by the wall of recess 17, the spring being interposedbetween said wall and the lug 1S, yield-ably resisting movement of thecarrier H toward the mandrel C, and yieldably retaining said carrier inengagement with stop J.

When assembling the guard into operative relation to a heel scouringmachine, the support F may be first adjusted so as to present the guardplate G at a position most convenient for the operator. This may beaccomplished by moving the support F circumferentially of the mandrel Cuntil in the adjusted position, whereafter the set screws 8 may beturned tight into engagement with hearing B. The shoe is then arrangedso that the portion 15 of plate G enters the rand, or space between theheel and upper of the shoe and, with motion imparted to the mandrel C,revolving the drum-like member I), the operator may move the shoe towardthe abradant on member D, slightly compressing the spring or device K.It is tobe observed that the carrier H together with the plate G may bemoved over the face 9 of support F, but there is no danger of anyportion of the upper of the shoe engaging the abradant, since theentrance of plate G into the rand of the shoe is sufficient to preventtwisting movement of the shoe which is apt to occur if a guard is notprovided and the abradant engages irregular or abnormally hard portionsof the heel.

Changes in details may be made without departing from the spirit orscope of our invention; but,
